Help "Authentication required"

[Blammo]

After upgrading to lollipop on my LG G2 I continue to get
"Authentication required Sign in with your email account:XXXX@gmail.com"
When I sign in it says in correct password.

I had disabled 2 step validations before I upgraded. The problem is it keeps asking me to Authenticate.
Any help is appreciated.

Try changing your password to a super simple one. You probably do know it but it might help.
